If a winning combination is achieved with a combination of symbols, it is possible to acquire more medals than the betted number, so that it is possible to enjoy a win / lose game with an interest in increasing the number of medals depending on skill and luck.

  Next, the structure of the main control board assembly 200 that houses the main control board 100 in the board case and the mounting structure thereof will be described. Here, FIG. 3 is an exploded perspective view of the main control board assembly 200, and FIG. 4 is a perspective view showing a state where the main control board assembly 200 is attached to the mounting bracket 300. The main control board assembly 200 mainly includes a board case including a case main body 210 and a case lid 260 and a main control board 100 accommodated in the board case.

  First, the case body 210 constituting one of the substrate cases is integrally formed of a transparent plastic as a substantially rectangular box that opens on the side that holds and accommodates the main control board 100. The main control board 100 has electronic components such as a CPU and a ROM mounted on one mounting surface, and the opposite surface serves as a reflow surface for soldering these electronic components, and the reflow surface is on the bottom surface of the case body 210. Oppositely, it is attached via a small screw or the like (not shown).

  On the upper end portion of the case body 210, hinge shaft portions 211 for hinge coupling with the case lid 260 are formed at predetermined three locations. Further, locking arms 212 each having a locking hole 212a and extending forward are formed at two locations on the lower end portion of the case body 210. In addition, a cylindrical container-shaped caulking opening 213 that engages the case lid 260 so as not to be detached again is formed at four predetermined positions at the lower end.

  Next, the case lid 260 is integrally formed of a transparent plastic as a substantially rectangular box that opens on the side facing the case main body 210. A hinge bearing portion 261 is formed at the upper end portion of the case lid 260 so as to be aligned with the hinge shaft portion 211 of the case main body 210 described above, and a locking arm 212 of the case main body 210 is formed at the lower end portion thereof. A locking projection 262 is formed for alignment.

  Further, at the lower end portion of the case lid 260, a caulking opening portion 263 having the same shape facing the caulking opening portion 213 of the case main body 210 is formed at a position where it is aligned. In addition, caulking openings 264 having the same shape as that described above are formed at four locations on one side of the case lid 260.

  Each of the caulking openings 263 and 264 is connected to the main body portion 265 of the case lid body 260 (the portion facing the case main body 210 and accommodating the main control board 100) via a cantilever connecting portion having a relatively small cross-sectional area. It is integrally formed with a little separation. Further, a projecting frame portion 266 that is substantially rectangular in a front view and projects from the main body portion 265 of the case lid 260 so as to surround the entire caulking opening 264 is integrally formed.

  The case main body 210 and the case lid body 260 are coupled to each other so that the hinge shaft portion 211 and the hinge bearing portion 261 are fitted to each other so as to be able to swing open and close. When the main control board 100 is accommodated and the case lid 260 is closed to the case main body 210 side, the locking hole 212a of the locking arm 212 is locked to the locking protrusion 262 of the case lid 260 and temporarily closed.

  In this state, the case main body 210 and the case lid 260 can be easily opened. Therefore, when mounted on an actual machine, the pair of caulking openings 213 and 263 at least at one location facing each other is shown in FIG. 3 is inserted and engaged inside. In this way, these case members are “crimped” together so that they cannot be re-detached, the cantilever opening 263 is cut off and the caulking opening 263 is separated from the main body portion 265 so that the substrate case cannot be opened. Yes. This makes it difficult to open the substrate case, and even if it is illegally opened, the trace remains.

  The main control board assembly 200 accommodated and assembled with the main control board 100 is attached to the back plate 2 a of the housing 2 via the mounting bracket 300. As shown in FIG. 3, the mounting bracket 300 includes a substrate portion 301 having a flat front surface on which a substrate case is placed, a rib 302 that is partially erected from the left edge or the lower edge of the substrate portion 301, and a substrate A support base 303 standing on the right edge of the part 301 and a sealing part 304 projecting further forward from the front surface of the support base 303 are mainly formed integrally.

  Note that the upper end side of the substrate portion 301 is greatly opened and is formed in a substantially U shape when viewed from the front. This ensures a required rigidity (mechanical strength) as the mounting bracket 300 and reduces the weight. Because.

  Screw holes 305 for fixing to the back plate 2 a of the housing 2 are formed in the substrate portion 301 at a plurality of predetermined locations. In addition, on the inner wall of the rib 302 on the left edge, two engaging recesses 306 are formed at the top and bottom, and a pair of locking arms 307 extending forward are formed on the upper and lower ends on the right side of the base plate 301. ing. Further, a caulking opening 310 having a cylindrical container shape is formed on the right side of the base plate 301 so as to face the caulking opening 264 of the case lid 260 and engage with the caulking opening 264 in a non-removable manner.

  The main control board assembly 200 engages the engaging arm 307 at the corner of the protruding frame portion 266 while engaging the engaging convex portion 267 formed on the left end portion of the case lid 260 with the engaging concave portion 306 of the mounting bracket 300. The locking protrusion 307a at the tip of the is locked. As a result, the main control board assembly 200 is stably held by the mounting bracket 300.

  At this time, the engagement medium 700 described above is inserted into and internally engaged with any pair of the caulking opening 310 of the mounting bracket 300 and the caulking opening 264 of the case lid 260. As a result, the main control board assembly (board case) 200 cannot be removed from the mounting bracket 300 unless the connecting portion of the caulking opening 264 is cut and separated from the main body portion 265, and it is difficult to execute illegal takeoff or the like. I have to. Further, even if the main control board assembly 200 is replaced with a modified product or the like, the fact can be quickly found by the destruction trace of the connecting portion of the caulking opening 264.

  As shown in FIG. 5, when the main control board assembly 200 is attached to the mounting bracket 300, the protruding frame portion 266 of the case lid 260 is placed on the support base portion 303 and the front surface of the protruding frame portion 266.
